Journal of Clinical and Nursing Research 2024年第4期8卷 22-29页

Introduction: Nursing ethical sensitivity refers to a nurse’s capacity for thoughtful consideration of ethical issues when faced with dilemmas. In the nursing domain, ethical dilemmas arise when nurses face challenges in making sound ethical decisions during clinical practice. These challenges may stem from conflicts between personal values and professional responsibilities. Methodology: Articles downloaded from Pub Med, CNKI, and Google Scholar were reviewed. Results: After rigorous screening, a meticulous analysis was conducted, encompassing 10 articles and involving a substantial cohort of 2863 participants. Existing literature revealed variations in the ethical dilemmas faced by nurses across different departments. The ethical sensitivity of nurses also varies, with higher ethical sensitivity correlating with stronger empathetic abilities. Zhen et al. classified the causes of ethical dilemmas into four main categories: (1) Ethical dilemmas arising from personal reasons of nursing students;(2) Ethical dilemmas stemming from the actions of teachers;(3) Ethical dilemmas triggered by patients;(4) Ethical dilemmas resulting from miscellaneous reasons. Conclusion: According to literature findings, nursing ethical sensitivity was positively linked to the nurse’s ethical decision-making ability. A case study-oriented teaching program has proven effective in enhancing ethical sensitivity among nursing students.

中国对外直接投资(outward foreign direct investment,OFDI)在推动中国经济与世界经济的深度融合、形成国内国际双循环发展新格局中有着举足轻重的作用。本文基于中国2005-2017年30个省份的面板数据,运用非期望产出的两阶段Super-SBM网络DEA模型以及结合全局ML生产率指数测算了中国各省份的工业绿色全要素生产率、生产效率和治污效率,并从理论和实证上考察了中国OFDI对三大效率的影响。研究发现:OFDI对三大效率的影响均表现为稳健的U型非线性关系;从作用机制看,短期内,OFDI对三大效率的抑制作用主要由于规模效应所致,长期内,OFDI对三大效率的促进作用主要通过结构效应和技术效应实现;从异质性视角看,我国东部和西部地区OFDI与三大效率呈显著的U型关系,中部地区的OFDI作用不显著,“一带一路”沿线省份的OFDI产生的正向效应早于非沿线省份。
